Interface AutoFitColumnRangeCallback

public interface AutoFitColumnRangeCallback

Specifies the range of columns to consider in the calculation of automatic sizes for cells. Implement this callback in your application if you want finer control over the range of columns that the view uses than is possible through the AutoFitColumnCount property. If no callback is registered with the GridView, then view uses the value of AutoFitColumnCount to determine the number of columns it considers in calculating sizes.

Method Detail

startAutoFit

public Range startAutoFit(int column)

Specifies the range of columns to consider when calculating sizes of cells in a GridView. The GridView calls this at the start of an autofit operation.

• If the first column in the returned range is less than zero, then the Gridview uses column zero as the first column in the range.
• If the last column in the returned range is greater than the last column in the data source, then the GridView uses the last column in the data access as the last column in the range.
• If the first column is greater than the last column, then the range is considered invalid, and no automatic size calculation takes place.
• If this method returns a null range, then the view uses the value of the AutoFitColumnCount to determine the range of columns to consider.

Parameters:

row - The first visible column of the GridView. If the GridView is not visible, then the GridView passes the the first column of the DataSource, which is column zero.

Returns:

The range of columns, inclusive, to use in calculating the automatic sizes.

endAutoFit

public void endAutoFit()

The GridView calls this method after it has finished calculating the automatic sizes.
